Instant messaging platform WhatsApp in its updated iOS app has added the support for biometric authentication, which will let users ‘lock’ the app with Face ID or Touch ID. The feature will be rolled out gradually globally.

To use this feature, users need to update the WhatsApp to the latest version, 2.19.20, from the Apple App Store, and then head to “Settings” –> “Account” –> “Privacy” –> “Screen Lock” on.

While it does not affect the display of notifications, the new update just adds a layer of security as you will not be able to be access the full app unless the standard iOS authentication process is successful.

WhatsApp now has over 200 million monthly active users in India and is also one of the popular cross-platform app worldwide.

In January, the company restricted forward messages to five chats globally down from 20 chats. The new change will continue to help keep WhatsApp focused on private messaging with close contacts.

The app has also introduced "Picture in Picture (PiP)" mode for Android users which allows them to view videos within a chat window, without opening third party pages or apps.

The app will soon receive dark mode on both the platforms – iOS and Android which will transform the whole of the visual appearance of WhatsApp to dark and will probably help you save battery.
